Newbe here. I just picked up a 1996 reg. cab short box step side. Has a 4.3 with a bad cam.....so I've been told. I already have a 2008 LC9 I intended on using for another project, but it has me eyeing it up for this one instead. I've tried to do a little searching on here and found some help. I am wondering if you guys can point me in the right direction. Truck already has a 4L60E 3 piece tranny. I have no electronics or accessories for the LC9. It looks like Nelson Performance makes a nice wiring harness. What else would I need for the swap?

1) Any of the 4.3 accesories swap over to the 5.3?
2) Can I use the same transmission?
3) What electronics should I be looking for at the junkyard?
4) Same radiator fan shroud work?
5) Any other wiring harness reccomendations?
6) Any other reccomendations?
